Eine sichere drahtförmige Lithiumionenbatterie enthält zwei Kompositgarne aus ausgerichteten mehrwandigen Kohlenstoffnanoröhren und Lithiumoxiden als Anode und Kathode. In der Zuschrift auf S. 7998 ff. beschreiben Y. Wang, H. Peng et al., dass die Kapazität dieser leichten und biegsamen Batterien nach 1000 Biegezyklen bei 97 % lag. Zudem wurden diese drahtförmigen Batterien zu Batteriegeflechten verwoben.
A stretchable wire‐shaped lithium‐ion battery is produced from two aligned multi‐walled carbon nanotube/lithium oxide composite yarns as the anode and cathode without extra current collectors and binders. The two composite yarns can be well paired to obtain a safe battery with superior electrochemical properties, such as energy densities of 27 Wh kg−1 or 17.7 mWh cm−3 and power densities of 880 W...
